Effects of bacteriocin and organic acid on growth performance, small intestine histomorphology, and microbiology in Japanese quails (Coturnix coturnix japonica)

In this study, 600 1-day-old Japanese quail chicks (Coturnix coturnix japonica) were used to investigate the effects of bacteriocin and organic acids on performance and intestinal histomorphology and microbiology. Chicks were allocated to 6 groups, i.e., control, Bac150 (150 mg/kg bacteriocin), Bac300 (300 mg/kg bacteriocin), OA (3 g/kg organic acid blend), Bac150+OA (150 mg/kg bacteriocin+3 g/kg organic acid blend), and Bac300+OA (300 mg/kg bacteriocin+3 g/kg organic acid blend) group. The trial lasted 35 days. At the end of the trial, a statistical increase was not observed in the performance parameters of chicks with feed additives. However, 300 mg/kg bacteriocin+3 g/kg organic acid supplementation given together has been found to have more positive effects on intestinal microbiology and histomorphology (P<0.05). Consequently, it is understood that the use of these feed additives together will achieve better results.
